JAMES A. MCGILLIRRAE, OF DYER, INDIAN.

IMPROVEMENT EN PRESSES.

Specification forming part of Letters Patent No. dlilll, dated January l0, 1835.

To all whom it may concern,.-

Be itknown that I, J Mins A. MCGILLIRRAE, of Dyer, in the county of Lake and State of Indiana, have invented a new and Improved Beater-Press; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying d-rawings, forming ypart of this specification, in which- Figure l, Sheet No. 1 is a side sectional view of my invention, taken in the line :c w, Fig. 2. Fig. 2, a horizontal section of the same taken in the line y y, Fig. l; Fig. 3, a detached perspective View ofY the trip-wheel by which the beater is operated. Fig. 4, Sheet No. 2, is a side elevation of the invention.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved press for baling purposes, and of that class which are provided with abeater for compacting in the pressbox the material to be pressed previousto the pressing operation.

The invention consists in a novel and improved means for operating the beater, and also in an improvement in the beater itself, as

well as an improvement in the means employed for pressing the article or material after the beating operation has been performed,where by certain advantages are obtained which will be hereinafter set forth.

A represents an upright framing, in which the press-box B is iitted, having doors C at two opposite sides of it. In the lower part of this framing, underneath the press-box, there is placed a horizontal sltaft, D, which has ropes DX attached to itat opposite points, so as to wind upon it in opposite directions, said ropes projecting from opposite sides of the shaft, and being connected to the lower ends of levers E E, the upper ends of which are connected by pivots t to the under side of the followerV F in the press-box, as shown clearly in Fig. 1. The lower ends of thelevers E Eare provided with rollers G, which travel on inclined ways H, the latter projecting upward from their outer toward their inner ends underneath the follower, as also shown in Fig. l. By this arrangement it will be seen that in the operation of the press I combine the lever with the inclined plane and obtain a quicker movement of the follower, and one attended with less friction, as there is less lateral press ure ou the follower than when the lower ends of the levers travel over horizontal surfaces, as in the ordinary presses of this kind.

I represents the beater,which works within the press-box B, and is constructed of cast-iron with holes b in its bottom, to admit of the escape of air from the pressbox when the beater descends. (See Fig. l.) This beater has two arms, J J, attached to it by pivots c c, the latter passing through the lower ends ofthe arms, and each arm has a sheet-bar, d, projecting from its outer side at right angles. The two arms are connected by a toggle, K, to the joint e of which the hoisting-rope L is attached, the latter passing over apulley, M, on the top of the framing A and down underneath a pulley, j", at the lower part of the framing, and thence around a pulley, gx, on which a horizontal tripwheel, N, is fitted and allowed to rotate freely. This trip-wheel N has a concentric rim, h, on its upper surface near its edge. This rim is not a continuous one all around the wheel, a space, fi, being allowed between two ends, j j, one end, j, being beveled to form an inclined plane, and the other end, j', being rounded, but having a vertical position to form an up right ledge to catch against the rope Il. To the outer side of the rim 71., near the inclined end y', there is another inclined plane, k,which hasan opposite position to the inclined endg` of the rim 71., as shown clearly in Fig. 3. The trip-wheel N is attached to the upper surface of atoothed wheel, O, which is iitted loosely on the arbor g, andthe wheel N gears intoawheel, I), to the upper end of the shaft Q1 of which the power is applied.

On the shaft (L) there is placed loosely a drum, It, which has a lever, S, connected to it. By raising and lowering this lever the drum R maybe connected with and disconnected from the wheel I), any suitable clutch arrangement being used for the purpose. The levers E E are operated from this drum R by a rope, T,

passing from a pulley, U, on shaft D to drum It.

The operation is as follows: The substance or material to be vpressed and baled is placed in the press-box B, and the shaft Q being rotated, the drum R is, b y means of the lever S, kept out of gear with the wheel l?, so that the levers E E ofthe follower F will not be operated. The wheel N however is rotated and the end j of the rim 7L at each revolution of N Catches the rope L and draws upward the beater I, the rope being tripped from the rim by the inclined plane 7c, so as to allow the beater to drop after the wheel N has nearly made one revolution. By this arrangement the beating operation is performed by a continuous rotation ofthe drivin g-shaft,there being no back aetion in tripping` the rope. After the beating operation is performed, the beater is secured in the upper part oi' tliepress-box, the bars d of the arms J J fitting in holes l Z in the sides of the press-box. The drum R is then thown in gear with the wheel l?, and the le- Vers E E are actuated to perform the pressing operation.

rllhe holes b in the beater I'eonstitute an mportant feature of the invention, causing, by the escape of airi'roni the press-box, the beater to fall with a force due to its gravity.

l claim as new and desire to secure by Letters Patent- 1. The employment or use of a cast-metal beater, I, provided with holes b, to admit of the escape of air from the press-box, substan-
